We build free tools that solve small everyday problems fast. Today we're adding six new ones to purepdf.net — not PDF tools this time, but the calculators and counters people search for every day. Every tool below is free forever, works on phone and desktop, and needs no account.
1. Percentage Calculator
Percentages show up everywhere: discounts, tips, tax, grade scores, price increases. Our Percentage Calculator (https://www.purepdf.net/percentage-calculator) handles all the common forms in one place — what is X% of Y, X is what percent of Y, percentage increase or decrease between two numbers, and adding or subtracting a percentage from a figure. Type two numbers, get the answer instantly, with the formula shown so you can see how it was worked out.
2. Word Counter
Writers, students, and job seekers live by word counts. Paste your text into the Word Counter (https://www.purepdf.net/word-counter) and it counts words, characters (with and without spaces), sentences, and paragraphs live as you type. It also estimates reading time and speaking time, shows keyword density, and includes readability scores.
3. Random Number Generator
Need a random number between 1 and 100 for a draw or a game? The Random Number Generator (https://www.purepdf.net/random-number-generator) lets you set any range, generate multiple numbers at once, allow or block duplicates, and sort the results. It also includes a list shuffler mode and a coin flip.
4. Age Calculator
Enter your date of birth in the Age Calculator (https://www.purepdf.net/age-calculator) and get your exact age broken down into years, months, weeks, days, hours, minutes, and seconds. You can also calculate your age as of any past or future date, use the days-between-dates mode, see a countdown to your next birthday, and add or subtract dates.
5. Spin the Wheel
Can't decide? Let the wheel decide. Spin the Wheel (https://www.purepdf.net/spin-the-wheel) lets you add your own entries — names, choices, options — customize the colors, and spin. Great for picking a winner, choosing teams, or classroom activities. You can remove the winner after each spin and share your wheel with a link.
6. BMI Calculator
The BMI Calculator (https://www.purepdf.net/bmi-calculator) computes your Body Mass Index from height and weight (metric or imperial), shows which WHO category you fall into, and tells you the healthy weight range for your height. Note: BMI is a screening measure, not a diagnosis — treat it as a rough guide.
